cmake: replace the way clang-tidy verifies tests, fix issues found
Replace existing `mk-unity.pl` `--embed` workaround with running
`clang-tidy` manually on individual test source instead. This aligns
with how clang-tidy works and removes `mk-unity.pl` from the solution.

Also:
- mqttd: fix potentially uninitialized buffer by zero filling it.
  ```
  tests/server/mqttd.c:484:41: error: The left operand of '<<' is a garbage value
    [clang-analyzer-core.UndefinedBinaryOperatorResult,-warnings-as-errors]
    484 |       payload_len = (size_t)(buffer[10] << 8) | buffer[11];
        |                                         ^
  [...]
  tests/server/mqttd.c:606:45: error: The left operand of '<<' is a garbage value
    [clang-analyzer-core.UndefinedBinaryOperatorResult,-warnings-as-errors]
    606 |       topiclen = (size_t)(buffer[1 + bytes] << 8) | buffer[2 + bytes];
        |                                             ^
  ```
- sockfilt: fix potential out-of-bound pointer:
  ```
  tests/server/sockfilt.c:1128:33: error: The 2nd argument to 'send' is a buffer
     with size 17010 but should be a buffer with size equal to or greater than
     the value of the 3rd argument (which is 18446744073709551615)
     [clang-analyzer-unix.StdCLibraryFunctions,-warnings-as-errors]
   1128 |         ssize_t bytes_written = swrite(sockfd, buffer, buffer_len);
        |                                 ^
  ```
- clang-tidy: suppress bogus `bzero()` warnings that happens
  inside the notorious `FD_ZERO()` macros, on macOS.
